Idiopathic Intracranial Hypertension Without Papilledema: A Case Emphasizing the Diagnostic Value of Optic Nerve Sheath Ultrasound.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We report the case of a 45-year-old woman with obesity who presented with some features of idiopathic intracranial hypertension (IIH), including postural headache and pulsatile tinnitus, but notably without papilledema. Initial investigations, including optical coherence tomography (OCT) of the optic nerve and computed tomography (CT) of the head, were unremarkable, resulting in a delay in diagnosis. Due to persistent symptoms, optic nerve sheath diameter (ONSD) assessment via ultrasound was performed, revealing bilateral dilation. Subsequent magnetic resonance imaging (MRI) identified an empty sella and distension of the optic nerve sheaths. A lumbar puncture confirmed an elevated opening pressure of 30 cm H₂O, establishing the diagnosis of IIH. This case illustrates the diagnostic challenges of IIH in the absence of papilledema and emphasizes the emerging utility of optic nerve sheath ultrasound as a non-invasive tool to aid in the early detection of raised intracranial pressure.
